[PATCH 0/3] Add DRM pixel blend mode support to R-Car DU

[Takanari Hayama]

The series of patches adds support for DRM pixel blend mode to R-Car DU.
The current R-Car DU implicitly supports "Coverage" only.

Unfortunately, this changes the default blending mode of R-Car DU to
"Pre-multiplied" which is the default when pixel blend mode is
supported.
